continue automatically despite y/n prompt?

[Bill White <billw@wolfram.com>]

When I'm out of the office for the day I like to do this:

   (gnus-demon-add-handler 'gnus-demon-scan-mail 5 1)

which automatically retrieves email from various pop accounts, which
are set up like this:

(setq mail-sources 
      '((pop :server "someserver0"
	     :user "me0"
             :dontexpunge nil)
	(pop :server "someserver1"
	     :user "me1"
             :dontexpunge nil)
	(pop :server "someserver2"
	     :user "me2"
             :dontexpunge nil)
))


The problem is that some pop servers are unavailable at times.  

When a server is not available and a download is attempted, an error
is displayed in the minibuffer with a y/n prompt - something like
"Server is unavailable. Do you want to continue (y/n)?"  If I'm not
around to respond, gnus will wait for the keypress until I come in the
next morning and type `y'.  Meanwhile, while gnus is waiting, no mail
is downloaded.

How can I make gnus continue regardless of such errors?

Thanks -
